bodyor fuselage which is lightin weight Q and at the same time is strong and durable.

Second, to provide an improved aeroplane body or fuselage which is rigid and capable of withstanding very severe shocks or strains. I

Third, to provide an improved aeroplane body or fuselage which is well adapted to withstand varying weather conditions.

Fourth, to provide an improved aeroplane body which may be very rapidly and economically manufactured.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Fig. XV isa transverse section on a line corresponding to line 15-15 of Fig. XII.

In the drawing similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the body in the preferred embodiment of my invention is formed of a lower wall section or member 1 and an upper wall section or member 2 of multiple-ply veneer having out-turned or flanged edges 3 secured together with longitudinal members 4 between them. These wall members are molded or conformed into compound curves by an improved process which is the subject matter of another application to be filed by me, the veneer being formed of sheets of wood veneer unitedthroughout by a water-proof glue or cement which is also the subject matter of another application filed by me. The edge flanges and the strips L are united throughout by this same water-proof glue which is of such tionsconstitute reinforcing members and are also formed of multiple-ply veneer, annular fillets 9 being arranged at each side of the bulkheads or partitions and glued to the walls to assist in retaining them in position. I

At the rear of the rear cross partition 7 into a horizontal .plate 10 extending entirely across the'body and projecting at each the longitudinal members 4 are extended side to provide rudder members 11 on which the horizontal rudders 12 are pivoted.

Thevertical rudder ,l3 is pivoted on the vertical rudder member 14; which is secured in the rear end of the body above the horizontal plate 10, the upper section -of the body having a longitudinal slot 15 therein adapted to receive this member 14. The lower edge of the member 14 is secured to the plate'10.

The vertical rudder '13 has a hinge member 16 at its forward. edge, while the rudder member 14 has a coacting hinge member 17. These hinge members have a plurality of interlapping knuckles secured to tiple-ply veneer by lapping the members thereof upon the hinge member and gluing .thereto,see Fig. VIII. The rudder sections are conformed into compound curves as shown in Figs. VI, VIII and IX .'thereby increasing their strength and rigidity.

The inserted longitudinal members 4 and the cross plate 10, as stated, serve as reinforcing and bracing elementsfor the body. The cross partition plates also serve as effective reinforcing and bracing means and, owing to the shape of the body and the material from. which its formed, provides a body which is very light in weight and one which at the same time is strong and durable and capable of sustaining very severe shocks and strains.

The portion of the body of the front par- ,tition 5 constitutes a compartment 20 plementary sections or wall members, there being a pair of bottom members 24 and a pair of top members 25 having flanges 3 at their meeting edges secured upon the longitudinal strips 4 substantially as in the embodiment described, except that the strips 1 are not as 10."

The side and top strips are, however, ex-

tended to provide rudder members 11 and I 14". In this construction longitudinal side plates 25 are arranged in the its to compensate for the weakening o' the body caused by forming the openings 8 therein.

member flanges and extending outwardly providing horizontal rudder members, a

veneer plies and parts being united throughextended into. a transverse plate,

These plates 25 are also formed of multiple-ply veneer and are secured to the longitudlnal cleats 26 secured to the walls of the body. The arrangement of the vertical and horizontal rudders in this structure is that of the structure described.

My improved aeroplane car or body is, as stated, very strong and durable being well adapted to withstand varying weather conditions and is rigid and capable of withstanding severe shocks and strains.

I have not attempted to illustrate any mounting means as such means formno part of my present invention. I have not attempted to illustrate or describe certain modifications in structure which might be necessary or desirable to adapt my improvements to various designs of aeroplanes, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:' v l 90 1. An aeroplane body cigar-shaped in general form comprising upper and lower wall members formed of multiple-ply veneer and having integral edge flanges, said wall members being conformed in cross and 95 longitudinal section so that one member complements the other, a horizontal cross plate of multiple-ply veneer disposed at the rear end of said body between said wall vertical rudder member of multiple-ply veneer secured at its lower edge to said' horizontal cross plate and projecting. through an opening in the top wall member, and cross partitions 'of multiple-ply veneer fittin within and secured to the walls of they b0 y, the upper part of the body having a pit opening between said partitions, said no out by a water-proof glue.

veneer plies and parts being united throughout by a waterproof glue.

4. An aeroplane body comprising upper and lower sections formed of multiple-ply veneer conformed in cross and longitudinal section so that one section complements the other, a. horizontal cross plate disposed between said sections at the rear end of said body and extending outward .to provide horizontal rudder plates, and a vertical rudder plate secured at its lower edge to said horizontal cross plate and projectingthrou h an opening in the top section.

5. in aeroplane body comprising upper and lower sections formed of multlple-ply veneer conformed in cross and longitudinal section so that one section complements the other, a horizontal cross plate disposed between said sections at the rear end of said body and extending outward to provide horizontal rudder plates.

6. An aeroplane body comprising complementary wall members formed of multipleply veneer and having integral edge flanges, a longitudinal member of multiple-ply veneer extending across the body and disposed between and to which the edge flanges of said wall members are secured, and cross partitions of multiple-ply veneer fitting within and secured to the walls of the body,

the upper part of the body having a-pit opening between said partitions.

7 An aeroplane body comprising compleply veneer and having edge flanges, members disposed longitudinally between and to which said flanges are united, said members being extended into cross bracing elements, and cross partitions of multiple-ply veneer fitting within and secured to the walls of the body, the top of the body having a pit opening between said partitions.

8. An aeroplane body cigar-shaped in general form comprising upper and-lower wall 'members formed of mulptiple-ply veneer and having integral edge flanges, and

' a horizontal plate disposed between said edge flanges and extending across the body and outwardly beyond the walls of the body providing horizontal rudder members.
